Building a variable.

[Full Bleed]

I'm trying to create some local variables dynamically. Here is an example:

Code: Select all

[h: featNameList = "Anatomist, ArcaneStrike"]

[h: anatomistFeat = 1]
[h: arcaneStrikeFeat = 0]

[FOREACH (featName, featNameList), CODE:
	{
		[featName+"Selection" =  if (eval(featName+"Feat") > 0, 1, 0)]
	}
]

I'm trying to create "AnatomistSelection" and "ArcaneSelection" variables dynamically. But it's not actually adding the 0 or 1 value to it (in the FOREACH) for me to be able to call later.

Capital letters vs non capital, might be an issue and you need to use Wiki: set()

What ever appears to the left of the equals sign can't be an expression, it has to be a variable/property name.
As Wolph mentioned you can use set to get around this

Code: Select all

[set(featName+"Selection", if (eval(featName+"Feat") > 0, 1, 0))]

Alternatively you could use eval as follows

Code: Select all

[h: AnatomistFeat = 3]
[h: ArcaneStrikeFeat = 0]

[h: featNameList = "Anatomist, ArcaneStrike"]

[h: anatomistFeat = 1]
[h: arcaneStrikeFeat = 0]

[h,FOREACH (featName, featNameList), CODE:
   {  
      [val =  if (eval(featName+"Feat") > 0, 1, 0)]
      [var = featName+"Selection"]
      [assignment = var + "=" + val]
      [eval(assignment)]
   }
]

[AnatomistSelection]
[ArcaneStrikeSelection]

but its harder to follow and will be slower (although I doubt in this case make any noticeable difference).

Fortunately, that isn't the problem.

I was able to get it working with set though.

What ever appears to the left of the equals sign can't be an expression, it has to be a variable/property name.

That's good information to know... Getting it to work is one thing... knowing why it didn't work the way I was trying is another.

As Wolph mentioned you can use set to get around this

Code: Select all

[set(featName+"Selection", if (eval(featName+"Feat") > 0, 1, 0))]

And this looks better than the way I got it working!

Thanks guys.

You could also use a json object for that.

Code: Select all

[h: feats = json.set("", "Anatomist", 1, "ArcaneStrike", 0)]

[h: fields = json.fields(feats)]

[h, FOREACH (field, fields), CODE:
   {
      [set(field+"Selection", json.get(feats, field))]
   }
]

[r: AnatomistSelection], [r: ArcaneStrikeSelection]
